Timing chains rather than belts are used in the majority of the BMW X1’s engines. The timing chains in the BMW X1 are reputed to endure a very long time as long as you take care of repairs and oil changes.

Why would my BMW X1 require a new timing chain?
On a BMW X1, a timing chain or belt ensures that the crankshaft and camshaft are in sync with one another and that the valves open and close at precisely the right times to coincide with cylinder combustion.
The same purpose is performed by a timing chain as it does by a timing belt, however the timing chain is constructed of metal and resembles a bicycle chain. The chain is enclosed inside the engine and requires lubrication due to its composition. A timing belt is normally made of rubber and fiber, is dry, and is placed outside behind a timing belt cover.
Timing chains often last longer than timing belts do. Belts ultimately deteriorate, split, and fall apart, whereas timing chains can stretch and occasionally snap, although this often occurs much later than a timing belt would have done.
However, timing chains have shown to outlast the belt and may turn out to be a more cost-effective solution in the long run. Vehicle makers did start replacing timing chains with timing belts to lower engine noise and costs because belts were a less expensive alternative.
The timing chain in your BMW X1 may stretch or break over time, necessitating replacement in order to keep the engine operating.
You might experience power loss, engine backfiring, engine rattles, a rough idle, and unpleasant driving if a timing chain were to extend. As the timing drifts out of whack, the car will roughly operate. A timing chain rarely entirely breaks, but if it did, the engine would halt.
When it’s time to repair a timing chain, make sure to do it since it guarantees the engine stays running smoothly. Having the proper timing in an engine is crucial because it’s the only way they can run.
Does BMW employ a timing belt or chain?
So what distinguishes a timing chain from a timing belt? Both a timing chain and belt perform the same basic function. These mechanisms are created to maintain the relative position of the valves opening and closing to the position of the piston as the engine is running, regardless of whether you drive a Porsche, Mercedes Benz, or BMW with an internal timing chain, or an Audi or Volkswagen with an external timing belt. When a valve is opened at the incorrect time, it may come into contact with the piston and cause a catastrophic engine failure.
The piston will raise (building compression) and the valves will open precisely, allowing air and fuel to enter the combustion chamber and exhaust to depart in less than one thousandth of a second in an engine with perfectly timed ignition. When valves open or close prematurely or lately due to a timing issue, the piston will be driven into the valve, most frequently bending the valve and possibly punching a hole in the piston crown, rendering the engine worthless. These fixes could cost as little as $4,000 to $5,000 or, depending on the engine, much more.
An internal timing chain is used by brands including Porsche, BMW, and Mercedes-Benz. These chains are stronger and less prone to break on their own. The same outcome is more frequently experienced when other chain-holding components, including chain tensioners and chain guides, fail. Check engine lights and a rattling sound, which is typically heard while starting an engine, are early warning indicators of a breakdown.
Initially using timing chains, Audi and Volkswagen switched to an external timing belt in the 1980s, 1990s, and the majority of the 2000s. The timing belt is simpler to inspect and replace than the timing chain. Timing belt replacement often costs between $700 and $900, which is significantly less than timing chain replacement. On most models, this cost also includes the water pump. The external timing belt’s drawback is that, like all belts, it eventually wears out and needs to be replaced. Timing belts should typically be changed every 80,000 miles, or every five years. Each time they are serviced or at least once a year, these should be visually inspected.

When should a BMW X1 timing chain be changed?
The second is the 4-cylinder, normally aspirated and turbocharged petrol N12, N14, and later N16, N18 engine that was installed in the MINI Cooper and S models from 2006 to 2016.
Often, if the timing is allowed to jump too late, the exhaust valves will flex. Therefore, if the engine rattles after starting from cold, it is preferable to replace.
Due to damaged valve stem seals that allow engine oil to vacuum bypass into the cylinders, these engines are also vulnerable to excessive engine oil consumption. It is advised to replace the valve stem seals when the engine is disassembled to replace the timing chain. This will spare labor for this separate repair down the road. We have a unique tool that makes it possible to repair the valve stem seals without taking the cylinder head off.
The drive belt for the alternator may occasionally be cracked or worn out from aging. While this is being removed, it is advised that you replace it.
In some circumstances, we demand a labor deposit to reserve a timing chain replacement (often roughly 50% of the entire repair cost). This is because there have been so many appointments in the past that were cancelled or missed.
How much does a BMW X1 timing belt replacement cost?
Since many pieces must be removed in order to reach the belt, labor is where the true expense lies. Your best chance is to shop about and compare prices, but be prepared to pay anything between $409 and $919.
For a BMW X5, how much does a timing chain cost?
Timing chain tensioner replacement for a BMW X5 typically costs between $589 and $678. Estimated labor expenditures range from $324 to $408, while the cost of parts is between $266 and $270.
Which model year BMW has timing chain problems?
Many BMW customers now have a major issue with premature timing chain breakdown, which is frequently discussed in BMW internet forums, mentioned on BBC Watchdog, and highlighted on other media websites.
A timing chain design issue seems to impact a variety of BMW diesel engines built between 2006 and 2015. The engine timing chain is exceedingly fragile; over time, it stretches and eventually snaps.
BMW timing chains have broken on a variety of 1, 3 and 5 Series models, most frequently the N47 diesel. In addition, we restore BMW petrol engines, M57 and N57 diesel engines, and BMW Minis.
The timing chain is at the back of the engine compartment and is not meant to be repaired.
Does BMW offer timing chain repairs?
BMW provides a service bulletin for cars powered by the N63 4.4 liter V8 engine. According to BMW, the timing chains on the N63 have been discovered to stretch and wear out early, leading to early valvetrain wear and decreased engine performance.
A visit to the dealership is required to find the problem. BMW technicians will do a test procedure to see if the problem is specific to that engine. The dealers will exchange the chains and all related gear if necessary.
To find out if your automobile qualifies for repairs, contact the NHTSA at 888-327-4236, the local dealership, or BMW directly at 800-831-1117.

The issue: It has been discovered that timing chains on N63 engines stretch and wear out early, leading to early valvetrain wear and decreased engine performance.
BMW has developed a test process to detect the level of timing chain wear. With the N63 Customer Care Package, which is intended to guarantee proper long-term engine running, dealers will do this test. Dealers will replace the chain and any necessary auxiliary hardware, such as the chain tensioner and auxiliary hardware as well as the chain sprocket, as a result of this test. The oil and oil filter will be replaced, and technicians will update the onboard computer to notify drivers when it’s time for a reduced oil change interval.
Information regarding the warranty: If applicable, the certified pre-owned warranty or the new car limited warranty will cover this repair. The repair may be covered by an extended warranty in cases when the factory warranty has already run out.
Owners should call their local dealer and provide the VIN to find out if their car qualifies for repairs under this service bulletin. Call NHTSA at 888-327-4236 or BMW directly at 800-831-1117. Please refer to TSB No. 111614.
Will BMW cover the timing chain cost?
Depending on the mileage of the car at the time of service, the reimbursement scheme offers between 40% and 100% of the cost of repairs. If the repairs were carried out at a BMW center, there is no cap on the repair reimbursement.
How long is the lifespan of a BMW timing belt?
Although they can last up to 100,000 miles, it’s always a good idea to change them before that. The engine’s valves, pistons, and other internal components may suffer severe damage as a result of belt failure.
Which BMW engines are problematic with the timing chain?
The BMW 1-Series, 3-Series, and 5-Series vehicles manufactured between 2007 and 2009 have seen multiple instances of complete engine failure in the past year, according to Watchdog. The engine came to a complete stop as a result of the timing chains snapping, which was the cause of the problem.
Posted on June 12, 2013:
All of the moving components of an engine that cooperate to propel a car forward are connected by the timing chain. They must all function flawlessly together.
The N47 engine has a secret timing chain link at the back that engineers claim is a component of the engine that is meant to endure the lifetime of the vehicle and is thus never maintained.
However, if the timing chain malfunctions, a catastrophic engine failure might occur suddenly.
It’s difficult to correct. Drivers must at the absolute least replace the chain, but it’s more likely that a completely new engine, which may cost anywhere from PS500 and PS8,000, needs to be installed.
In 2011, Dan Greenwood purchased a pre-owned BMW 3-Series 320D. Despite having traveled almost 100,000 kilometers, it had a complete service history. The BMW name and the knowledge of the car’s past offered him assurance that he was making a reliable purchase.
The engine abruptly shut off while he and his young girls were traveling in slow traffic. He was informed that he would require a complete engine rebuild that would cost more than PS2,000 after being transported to a local mechanic where they looked at his car.
The automobile is no longer under warranty because it is five years old, so Mr. Greenwood said, “I was just surprised. I was looking at something that would cost thousands of pounds from what appeared like a simple mistake.”
How much does a BMW timing belt replacement cost?
Belts don’t cost a much by themselves. Since many pieces must be removed in order to reach the belt, labor is where the true expense lies. Your best chance is to shop about and compare prices, but be prepared to pay anything between $409 and $919.
